How to Tolerance for Tilts and Decenters of a Double Pass System

This article explains:
  • How to setup a double pass system for the purposes of tolerancing the tilts/decenters of elements.
  • How to setup the Tolerance Data Editor with the user-defined operands (TU**) required for accurately modeling lens tilts and decenters in double pass.
  • How to verify that the double pass system has been adequately modeled to reflect reality.

How to Analyze Your Tolerance Results

Many times it is useful to analyze your tolerances in detail.  In Zemax's tolerance analysis, you may save the tolerance results for each Monte Carlo file, or you may save each tolerance in the sensitivity analysis indidvidually in Zemax file format.  This article describes how to take a closer look at what Zemax does internally to model each and every tolerance in your design.
